Fix compile error with clang 3.8
When compiling with clang 3.8 (default clang version on Debian Stretch, the current stable), we get errors like this: CXX dtrace-probe.o ../../binutils-gdb/gdb/dtrace-probe.c:103:31: error: default initialization of an object of const type 'const dtrace_static_probe_ops' without a user-provided default constructor const dtrace_static_probe_ops dtrace_static_probe_ops; ^ Silence them by value-initializing those objects. It's not necessary with other compilers (later clang versions, gcc), but it shouldn't hurt either.
